I'm a newbee

Hi , I am trying to figure out this MFP program. So far, I think it's what I need to help get myself back on track....
I am cruising to 50 (May) and battling weight loss. I am 5'6" female 155 lbs. My goal weight is 130. I have a personal trainer I work with twice a week for strength training - going on year 2 as of November, I jog average 2 miles three times a week, I kayak 17 miles runs periodically-sometimes more sometimes less, I changed my diet to vegetarian (1,400 cal./day) and yet I have not lost a pound nor have I dropped a pant size. Anyone facing similar challenges? I could really use some advise...
